主 题：Hip arthroplasty Acetabular fixation With screw Without screw Operation time
摘 要：AIM To compare the operation time, blood loss, and early outcomes of acetabular components with and without the *** Thirty patients who underwent cementless acetabular component with or without screw and whose follow-up exceeded one year period in total hip arthroplasty were evaluated. A posterior approach was used in all surgical procedures by one experienced surgeon. Demographic data, operation time, intra-and postoperative blood loss volume, follow-up clinical score, cup migration, and osteolysis were recorded. The Kolmogorov-Smirnov test was performed for testing the normality of study data. Mann-Whitney U test was used to analyze the intergroup differences. A P-value of ≤ 0.05 was considered statistically *** Acetabular components were used in 16(53.3%) patients with screw and 14(46.7%) without screw. After one year of follow-up, an osteolytic lesion of 3 mm was found in only one patient in the screw group. No cup migrationwas encountered. Intra-group mean Harris hip score significantly increased, but there was no significant intergroup difference. While the mean operation time of the screw group was 121.8 min(range; 95-140), it was 102.7 min(range; 80-120) in the no-screw group, and this difference was statistically significant(P = 0.002). The mean intraoperative/postoperative, and total blood loss were 556.6 mL(range: 350-800)/423.3 mL(range: 250-600), and 983.3 mL(range: 600-1350), respectively in the screw group; and 527 mL(range: 400-700)/456 mL(range: 230-600), and 983 mL(range: 630-1250), respectively in the no-screw group. The blood loss difference between the two groups was not significant. In the screw group, the operation time was 19.1 min longer than the no-screw group, and this difference was statistically *** Acetabular components with or without screw have similar results, but the use of screw increases the operation time significantly, while not changing the blood loss volume.
